Prepare the area by cutting the existing grass to the lowest sword height possible.
The surface must be as even and solid as possible.
The material in the ground should allow for good growth for the grass. If the area has natural grass but the ground is too compacted, aerate the entire surface to ensure a successful installation. Add sand 0-4mmand mix with the aerated soil afterwards.
If you build from scratch ideally the top 100 mm will be a 50/50 mix of soil and sand 0-4 mm.
The surface should be solid, If the surface is too soft the surface will be uneven during the installation from walking and anchoring the installation pins. When you walk on it your foot should not sink in the ground. A footprint is ok since CoverLawn® will protect the surface when the rolls are in place. The surface should be so solid that when you walk on it the footprint depth is max 5 mm.
Leave top dress 5 kg /m2 that you need after the installation. Sand size 0-4 mm.
